This document contains Electrical Calculations for the Togus VA Medical Center Laundry HVAC Replacement project (Project No. 0506-0018), prepared by Miller-Remick LLC on 01/26/2023. The calculations include a Building Electrical Load Calculation and a Lightning Protection Risk Assessment.

The electrical load calculation details equipment specifications for various HVAC components, including voltage, phases, full load amps, and horsepower. The total new mechanical connected load is 176.47 kVA, with 10.00 kVA for miscellaneous connected loads. The grand total building connected load is 265.94 kVA, and the existing service transformer size is 300.00 kVA. The lightning protection risk assessment using NFPA 780 methodology indicates that a lightning protection system is not required for this facility, based on factors such as the building's equivalent collection area, height, lightning flash density, and location-specific risk coefficients.
